Abstract
Fiftyโeight urine samples were collected during the grazing season from cattle at North Wyke. N, K and Na contents, pH, specific gravity and osmotic potential were measured. Significant correlations were found between many of these variables. Wide ranges in N, K and Na contents occurred, indicating considerable variation in the rate of return of these nutrients between urine patches. The low osmotic potential of some samples suggested the involvement of an osmotic effect in urine scorch.

Restriction endonucleases were used to show the excretion of an identical strain of cytomegalovirus (CMV) by two brothers over a 25-yr period. The same enzymes were used to show that the younger brother, case report, excreted an adenovirus over at least a 3-mo period. We are unable to determine the
